Expanded Information:

Sowing seeds is sexual reproduction. Since natural hybridization has a very low fruiting rate, artificial pollination is usually necessary to increase the fruiting rate of azaleas and to obtain a larger number of seeds.

The main practice is in the azalea bloom time, select the growth of good, flower color beautiful robust parent, moved to the greenhouse, each pot to choose to stay in the flowers of large, early flowering flowers 3-4, remove the stamens and flowers near the new shoots, so that the nutrients are concentrated, to be to the stylopodium mucus, that is, a new brush dipped in the parent's pollen to paint a few times on the line.

A week after pollination, the pot will be moved to the outdoors, strengthen the water, fertilizer management, after about 5-6 months of growth and development, in November-December you can see the fruit gradually from green to brown, the seeds are ripe. Then it will be picked off, let it dry, raise clean, placed in a cool ventilated place.

Azalea seeds are very small and should not be stored for a long time, otherwise the germination rate is low. If it is evergreen azalea seeds, that should be picked with the seed, sown in a pot in the greenhouse; if it is deciduous azalea seeds, can be put into the next spring sowing.
